Disability Tax Credits and Benefits for Landau-Kleffner Syndrome (LKS)


There are many neurological disorders prevalent in society. Landau–Kleffner syndrome (LKS) is one that has a significant impact on children. Children who are affected by the syndrome find it difficult to understand or express thoughts in their own language. Not all affected children are born with the condition. In certain cases, a child who normally has good vocabulary may suddenly find it difficult to speak and understand language. LKS affects children who are found to have abnormal electrical waves within their brain and it is normally seen in children within the ages of 3 to 7. In most cases, it affects either the understanding ability or speaking ability, but in some circumstances, it affects both abilities of a child. Parents and family members of children who have been affected by Landau–Kleffner syndrome can apply for the Disability Tax Credit and other benefits offered by the Canadian government.


The exact cause of Landau–Kleffner syndrome has not been identified. Almost all the children who acquire LKS seem to be perfectly fine until they are exposed to regular spoken language. However, the condition’s existence can be found with the help of an EEG, which tests for the abnormality of electrical waves within the brain. Landau-Kleffner is not seen as an inherited syndrome, since most children affected by LKS do not have it in their family history.


Most children with Landau–Kleffner syndrome tend to exhibit similar symptoms:

  • Without any specific reason, the children may tend to have problems understanding or speaking their language
  • The gradual decrease in the ability to speak which might eventually lead to the complete loss of speaking ability
  • Problems in communication, which might lead to the development of behavioural or psychological problems
  • Before a child acquires LKS, they may experience fits at night
  • As the child grows, the occurrence of fits will stop eventually
  • Children may tend to express their thoughts using sign language or written communication
  • The child may exhibit symptoms of hearing loss, but tests show that hearing capacity is perfectly fine
  • Slow development of the children in terms of communication and social behaviour

Disability Tax Credits for Landau–Kleffner Syndrome (LKS)

There are not many treatment methodologies available for Landau–Kleffner syndrome (LKS). The use of medicine to decrease the abnormality of the electrical waves within the brain does not have much effect. The use of corticosteroids has been tried by many researchers and fortunately, it has improved the speaking ability of certain children. However, it does not serve as a cure, since certain children do not show any positive effect with the use of these steroids.

Parents and other family members of children with Landau–Kleffner syndrome should look into applying for disability tax credits and other tax benefits provided by the Canadian government. An affected child may qualify under the categories of mental functions and speaking. A representative from HandyTax can guide your through the process and maximize your claim!
